That line of code does not appear in templates/article/dublincore.tpl in OJS 2.4.2; either your cache directory is out of date (check file permissions on cache/t_compile and clear its contents) or there is some out of date code in your installation.

Look at the templates/article/dublincore.tpl file as it appears in the OJS 2.4.2 download package, then look at the same file in your installation. If you've upgraded to 2.4.2, they should be the same (either using the patch method or the full package method). I can't tell you why these are different in your installation because I don't know its maintenance history, but as long as you're mixing old code and new code, your installation is likely not to work.
